The modulation used by access net 200 and Multiple Access scheme can change according to the certain telecommunications standards disposed.? In LTE ULL LTE application, OFDM can be used on DL, and uses SC-FDMA on UL, to support that frequency division is double Both work (FDD) and time division duplex (TDD).As those skilled in the art easily appreciate that according to following detailed description , each conception of species proposed in this paper is highly suitable for LTE application.But these concepts can be readily extended use Other telecommunication standards of other modulation and multiple access technology.For example, these concepts can be extended Evolution-Data Optimized (EV-DO) or Ultra-Mobile Broadband (UMB).EV-DO and UMB is by third generation partner program 2 (2GPP2) publication, conduct The air-interface standard of a part of CDMA2000 family of standards, and connect using CDMA to provide broadband internet to movement station Enter.These concepts can also be extended to other modifications (for example, TD-SCDMA) using wideband CDMA (W-CDMA) and CDMA General land wireless access (UTRA)；Use the global system for mobile communications (GSM) of TDMA；And the evolution using OFDMA Type UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20 and flash OFDM.? UTRA, E-UTRA, UMTS, LTE and GSM are described in document from 3GPP tissue.It is retouched in the document that 3GPP2 is organized CDMA2000 and UMB are stated.The actual wireless communication standard and multiple access technology used will depend on concrete application and apply to system The overall design constraints added.

ENB 204 can have the mutiple antennas for supporting MIMO technology.ENB 204 enabled to using for MIMO technology Spatial reuse, beam forming and transmitting diversity are supported using spatial domain.Spatial reuse can be used to same on the same frequency When send different data flows.Data flow can be sent to single UE 206 to increase data rate, or be sent to multiple UE 206 is to increase entire system capacity.This is by carrying out spatial pre-coding (that is, using to amplitude and phase to each data flow The scaling of position), and then each stream through spatial pre-coding is sent on DL to realize by multiple transmitting antennas.Reach UE 206 data flow through spatial pre-coding has different space characteristics, this makes each UE 206 in UE 206 can Recover the one or more data flows for going to the UE 206.On UL, each UE 206 sends the data through spatial pre-coding Stream, wherein the data flow through spatial pre-coding enables eNB 204 to identify the source of each data flow through spatial pre-coding.

Spatial reuse is usually to use when channel conditions are good.When channel conditions are less advantageous, wave beam can be used Forming will transmit energy and concentrate in one or more directions.This can be by carrying out the data sent via mutiple antennas Spatial pre-coding is realized.In order to realize good covering at cell edge, can come in conjunction with transmitting diversity using single stream Beam-forming transmission.

In the following detailed description, the mimo system referring to the support OFDM on DL is described to each side of access net Face.OFDM is a kind of spread spectrum, which modulates data on multiple subcarriers in OFDM symbol.These subcarriers are pressed It is opened according to accurate frequency interval.The interval provides and allows a receiver to recover the " orthogonal of data from these subcarriers Property ".In the time domain, protection interval (for example, cyclic prefix) can be added to each OFDM symbol, to prevent from doing between OFDM symbol It disturbs.The SC-FDMA with discrete Fourier transform (DFT) extension ofdm signal form can be used in UL, to compensate high peak value With average power ratio (PAPR).

Fig. 7 be show for manage the ULL in wireless communication system communication ULL time shaft 700,702 it is unrestricted The figure of property example, wherein in the figure, the time extends from left to right.In this example embodiment, time shaft 700,702 includes the every of subframe The ULL frame of the symbol duration of a symbol.Time shaft 700,702 describes: indicating to control for ULL physical down link The symbol of the TTI of channel (uPDCCH) and/or ULL physical down link sharing channel (uPDSCH) and expression include The symbol of the TTI of uPUCCH and/or uPDSCH.In time shaft 700,14 symbols are shown in given subframe 712 710,711 etc. (for example, for conventional CP), and in time shaft 702,12 are shown in given subframe 722 A symbol 720,721 etc. (for example, for extending CP).In any case, by using based on symbol TTI (with The TTI based on subframe in LTE is opposite), lower time delay is realized in ULL.It should be appreciated that in other examples, TTI can be two or more symbols, time slot (in the case where subframe includes two time slots) of subframe etc..In addition, HARQ The process response time can be based on the duration of the ULL TTI communicated, in multiple symbols (for example, 3 symbols, 4 symbols etc. Deng), multiple glossary of symbols (for example, 3 double signs, 4 double signs etc.), multiple time slots are (for example, 3 time slots, 4 time slots etc. Deng) magnitude on.In the illustrated example, the duration of ULL communication is 1 symbol, is sent in the symbol 0 of subframe UPDCCH/uPDSCH, and in the symbol 4 of subframe handle and send HARQ etc..Therefore, continue also based on the TTI of shortening Time, compared with the corresponding HARQ time delay in LTE communication, time quantum associated with the HARQ time delay in ULL communication is less.

Fig. 8 shows the exemplary frame structure 800 for ULL LTE (and/or LTE) communication.For example, as described, frame Structure 800 can indicate a symbol duration TTI (for example, symbol 710,711,720,721 in such as Fig. 7 etc. it OFDM, SC-FDM of class or a symbol duration of simileys), two or more symbol durations TTI, time slot hold Continuous time TTI etc. is indicated with frequency (and as described in the horizontal direction with time) in vertical direction.No matter How, the frame structure for ULL can be provided in current LTE UL frame structure.For example, frame structure 800 wraps at the end of frame The domain PUCCH 802 (for example, in uplink frequency bandwidth) for including LTE, in this example embodiment, not by ULL LTE frame structure Interference.More precisely, providing ULL frame structure in the domain PUSCH 804 in LTE.

As shown in this example embodiment, optionally kept in the domain LTE PUSCH 804 in the domain LTE PUSCH 806 at least It is some, and include the domain uPUCCH 808 and the domain uPUSCH 810 also in the domain LTE PUSCH 804.In the exemplary frame structure 800 In, the domain uPUCCH 808 is similarly disposed at the end in the domain LTE PUSCH 804 that can be used for ULL.It can be by the domain LTE PUSCH 804 remainder is divided into the domain PUSCH 806 and the domain uPUSCH 810 (for example, scheduling based on eNB or other network nodes). It should be appreciated that virtually any of frame structure can be used, LTE and ULL are coexisted among given TTI. In addition, eNB can be distributed to one or more UE and be provided according to the region in frame structure 800 as described in further citing herein Source (and LTE and/or ULL therefore can be supported to communicate), and by using the resource such as distributed from eNB to the UE, it receives Square UE may be somewhat unknowable for the frame structure.

Fig. 9 shows the exemplary frame structure 900 for ULL (and/or LTE) communication.For example, as described, frame structure 900 can indicate a symbol duration TTI (for example, symbol 710,711,720,721 in such as Fig. 7 etc. A symbol duration of OFDM, SC-FDM or simileys), two or more symbol durations TTI, time slot when Between TTI etc., indicated in vertical direction with frequency (and as described in the horizontal direction with time).No matter such as What can provide the frame structure for ULL as described in current LTE UL frame structure.For example, frame structure 900 is in frame It include the domain PUCCH 802 of LTE at end, in this example embodiment, not by the interference of ULL LTE frame structure.More precisely, ULL frame structure is provided in the domain PUSCH 804 in LTE.

In this example embodiment, the RB that can be used for ULL can be specified to: can be used for total RB (N of UL communication in TTI_RB ^UL) subtract Remove offset (N_RB ^Offset), wherein N_RB ^OffsetIn the combined size and ULL LTE that may be intended to adapt to the domain PUCCH 802 in LTE The possible domain uPUCCH.The RB that can be used for ULL communication can also be further divided into multiple RB groups (for example, RB group 902), they can be continuously in frequency, and may include multiple RB (for example, RB 904).In this example embodiment, it shows 4 RB groups of 14 RB (for example, extraordinary image LTE, but a symbol duration, two or more symbol durations, RB is divided in time-slot duration etc. rather than sub-frame duration).It can correspondingly be dispatched on the RB in these RB groups UPUCCH and/or uPUSCH communication (for example, according to frame structure 800).

It gives one example, each RB group 902 may include the RB of 2,3,5 etc. multiple, wherein every group in RB quantity It can be equal or not etc..For example, the quantity of the RB in RB group can be the start offset (N based on configuration_RB ^Offset), needle To the TTI uPUSCH bandwidth determined etc..A specific example for realizing the RB group size of certain system bandwidths can be with It is as follows:

UPUSCH bandwidth (RB)	RB group size
		96	{24,24,24,24}
88	{20,20,24,24}
		80	{20,20,20,20}
72	{18,18,18,18}
		64	{16,16,16,16}
56	{12,12,16,16}
		48	{24,24}
40	{20.20}
		32	{16,16}
24	{24}
		16	{16}
12	{12}

In addition, for example, the quantity of RB is for certain sign patterns (for example, not including the symbol of detection reference signal (SRS) (being also known as " non-SRS symbol " herein)) for can be it is similar, but really including SRS sign pattern symbol (herein also Referred to as " SRS symbol ") it can have multiple RBs associated with specific SRS bandwidth.For example, for 5/10/15/20 megahertz (MHz), the SRS bandwidth specific to cell of current LTE can be as following: 5MHz supports 36/32/24/20/16/12/8/ 4 RB are used for SRS, and 10MHz supports 48/40/36/32/24/20/16 RB to be used for SRS, and 15MHz supports 72/64/60/48/ 40/36/32 RB supports 96/80/72/64/60/48 RB to be used for the SRS specific to cell for SRS and 20MHz.This Outside, in one example, it can be based in part on the bandwidth for the SRS in ULL, correspondingly adjustment is used for the RB of uPUSCH And/or the quantity of RB group, wherein uPUSCH includes the SRS specific to cell.It is noted that for working as specific to cell UPUSCH can be supported in SRS symbol or can not be supported to the case where when SRS bandwidth is smaller (for example, 4 RB or 8 RB) Transmission.Alternatively, in this case, it can support uPUSCH, but can not follow such as the RB group in non-SRS symbol Management.For example, if the SRS bandwidth specific to cell is 16 RB in 100RB uplink bandwidth, then it can be by not The SRS bandwidth specific to cell including 16RB, and remaining 84 RB are divided into 4 groups, to be assigned to uPUSCH.It lifts again One example, if the SRS bandwidth specific to cell is 16 RB in 100RB uplink bandwidth, then can by by this 16RB is used as a group, and remaining 84 RB are divided into 3 other groups, to be assigned to uPUSCH.

Anyway, eNB can be according to based on one in the TTI for using frame structure 800 and/or 900 illustrated above Or the corresponding RB quantity in multiple RB groups is the bandwidth that uPUSCH is determined, assigns resource to one or more UE.

Figure 10 shows the Exemplary temporal axis 1000,1010 for the RS transmission in ULL communication.Time shaft 1000 includes The transmission of uPUCCH/uPUSCH 1004 in ULL frame, the ULL frame have the symbol duration in LTE subframe.In addition, In time shaft 1000, ULL RS (being also known as uRS) transmission 1002 is depicted at different symbols.It should be appreciated that It as described, can be without in the case where transmitting uPUCCH and/or uPUSCH, there is the transmission to the uRS for given UE. In time shaft 1000, the transmission of uRS be can be regularly (for example, every 6 then 9 symbols), but transmission be also possible to it is non- Regularly.In any case, as described further below, the triggering of uRS transmission can be specified by eNB (for example, such as this Text description, for UE one or more grant of resources in or other way).

Time shaft 1010, which depicts the received uplink at symbol 1012, permits, and can specify in symbol 1014 UPUSCH transmission in uRS transmission and symbol 1016.In this example embodiment, the transmission of uRS can be non-periodically, so that the uplink (and therefore, uRS is to be based on receiving uplink allowance, without inevitable ground in some for the transmission of link allowance triggering uRS Period).In one example, the transmission of the uRS in symbol 1014 can be related to the transmission of the uPUSCH in symbol 1016 Connection.For example, in the case that the uPUSCH transmission and uRS in the grant of resources designated symbols 1016 in symbol 1012 trigger, UE It can determine in symbol 1014 in front based on the uRS triggering received in the allowance and send uRS.In this regard, For example, the triggering can specify before permitting the related symbol for sending uRS with the uplink resource symbol (or More generally useful, TTI) quantity.Although it is not shown, but can be transmitted in the case where not triggering uRS using another uPUSCH To dispatch identical UE (for example, the just symbol after symbol 1016).In this case, uPUSCH transmission may rely on URS in symbol 1012 is demodulated.Although it is not shown, but being also possible in the feelings for not having adjoint uPUSCH or uPUCCH Under condition, uRS transmission is dispatched in one or more symbols.

It should be appreciated that transceiver 1206,1256 can be configured as by one or more antennas, the front end RF, One or more transmitters send and receive wireless signal with one or more receivers.In one aspect, transceiver 404, 454 can be tuned to be operated at specified frequency, allow UE 1202 and/or eNB 1204 in some frequency Place is communicated.In one aspect, one or more of processors 1203 can configure transceiver 1206 and/or one or more A processor 1253 can configure transceiver 1256 with based on configuration, communication protocol etc. according to specified frequency and power level Operation, so as to respectively related uplink or downlink communication channel upload serve downlink signal 1208 and/or under Downlink signal 1209.

In one aspect, transceiver 1206,1256 can be operated in multiple frequency bands (for example, using multiband-multi-mode Modem is not shown), to handle the numerical data sent and received using transceiver 1206,1256.A side Face, transceiver 1206,1256 can be multiband, and be configured as supporting multiple frequency bands for specific communication protocol. In one aspect, transceiver 1206,1256, which can be configured as, supports multiple operation networks and communication protocol.Thus, for example, receiving Hair machine 1206,1256 can be configured with modem based on a specified to realize the transmission and/or reception to signal.

In an example of scheduling ULL resource, Figure 13 show to come for ULL grant of resources based on the received (for example, By UE 1202) send the method 1300 communicated.At box 1302, it is quasi- that UE can receive uplink resource from network entity Perhaps, to be communicated in the wireless network.Grant of resources receiving unit 1210 (Figure 12) can be from network entity (for example, eNB 1204) it receives uplink resource and permits (for example, uplink resource permits 1280), to be communicated in the wireless network. For example, as described, uplink resource can be permitted sending out as down link signal 1209 by eNB via transceiver 1256 UE 1202 is given, transceiver 1206 can be received and provide it to one or more processors 1203 and be handled.Example Such as, which can correspond to ULL grant of resources, can be according to ULL frame structure come regulation ULL grant of resources, wherein ULL Frame structure with have the duration more less than the duration of traditional wireless communication technology (for example, a symbol of LTE subframe Duration, two or more symbol durations, time-slot duration etc.) TTI it is corresponding.It gives one example, it can be with According to ULL frame structure 800 (Fig. 8) described above and/or 900 (Fig. 9) come regulation ULL grant of resources, and therefore, ULL money Permit to include multiple RB and/or RB groups in the TTI in source.In addition, for example in this regard, grant of resources formation component 1220 (Figure 12) can generate the grant of resources for UE 1202 (for example, in UE 1202 and eNB according to ULL frame structure In the case that 1204 can be operated based on the ULL frame structure, for specifying money in the allowance based on the ULL frame structure Source), and dispatch component 602 can via transceiver 1256 to UE 1202 transmission (for example, send) grant of resources, so as to It is received by grant of resources receiving unit 1210 via transceiver 1206.

For example, uplink resource allowance is received at box 1302 can be optionally at box 1304, from net Network entity receives multistage grant of resources.Grant of resources receiving unit 1210 can be from network entity (for example, eNB 1204, core Heart net 130 etc.) the multistage grant of resources is received, it may include in the multiple individual downlinks sent by transceiver 1256 The multistage grant of resources is received in link signal 1209, receive and by one of UE 1202 by transceiver 1206 Or multiple processors 1203 are handled.For example, may include more by the grant of resources that grant of resources formation component 1220 generates Phase resource is permitted, so that scheduling component 602 sends Grant information to UE 1202 in multiple examples of communication.For example, In one stage grant of resources, grant of resources formation component 1220 may include one or more parameters, wherein one or more A parameter may include the modulation permitted for uplink and encoding scheme (MCS), for the uplink from UE 1202 The transmission power control (TPC) and/or precoding information of communication.First stage money can be sent to UE 1202 by dispatching component 602 Source is permitted, wherein grant of resources receiving unit 1210 can (for example, via communication component 661) to receive first stage resource quasi- Perhaps.In a specific example, first stage grant of resources can be length be 10-13 bit, and can via PDCCH, Enhanced PDCCH (EPDCCH) etc. sends from eNB 1204 to UE 1202.For example, being used for uplink in permitting in the first stage The MCS that link circuit resource is permitted can be 5 bits, and TPC can be 2 bits and precoding information can be 3-6 bit.

In second stage grant of resources, grant of resources formation component 1220 may include one or more other ginsengs Number may include: to be used to indicate the new data indicator that UE 1202 is the previous communication or new traffic of retransmission (NDI), it is used to indicate the HARQ procedure mark of HARQ procedure involved in the NDI, the MCS is used to indicate and provides in the first stage Source permit in sent with signal form the change of MCS increment (delta) MCS, be used to indicate and to be applied to when sending RS The RS cyclic shift of the cyclic shift of resource block in the resource of allowance, ULL RS triggering indicator (for example, for trigger such as by The one or more situations or related parameter for the RS transmission that RS trigger assembly 1224 prepares, will further retouch herein State), the channel state informations (CSI) of the one or more situations or non-periodically in relation to parameter that are used to indicate report CSI trigger, And/or the instruction for the resource permitted.Grant of resources receiving unit 1210 can receive multiple rank via communication component 661 The appointment of section, and communication component 661 can be configured using specified parameter in the appointment in multiple stage come to eNB 1204 send communication (for example, using MCS, using TPC, include RS, the transmission when detecting triggering according to RS cyclic shift CSI etc.).In specific example, second stage grant of resources can be 10 bits comprising: it is to use for distinguishing the allowance In downlink or the bit (it is 1 bit) of uplink, the NDI as 1 bit, the increment MCS as 1 bit, 1 ratio Special RS cyclic shift (it can be demodulation RS (DM-RS) cyclic shift) (for example, being used to indicate is to be directed to the communication of order 1, The cyclic shift that DM-RS is realized between symbol 0 and 6 is still directed to the communication of order 2, realizes DM-RS between symbol 0/6 and 3/9 Cyclic shift), the uRS of 1 bit triggering instruction, the non-periodically CS triggering of 1 bit and/or the resource allocation of 4 bits.

In addition, in one example, receive uplink resource at box 1302 and permit, it can be optionally in box At 1306, TBS scaling instruction is received from network entity.Grant of resources receiving unit 1210 can from network entity (for example, from ENB 1204) receive TBS scaling instruction.Thus, for example, can wrap by the grant of resources that grant of resources formation component 1220 generates It includes: based on the instruction scaled in the grant of resources to the TBS of the RB size distributed of UE 1202.Therefore, grant of resources reception group Part 1210 can receive TBS scaling instruction, and TBS determines that component 1214 can be based at least partially on TBS scaling and refer to The bandwidth shown and/or distributed in grant of resources determines the TBS size for being communicated using ULL resource.Alternatively or separately Other places, TBS determine component 1214 can based on one or more other parameters (for example, measurement gulped down with what eNB 1204 was communicated The amount of spitting, for availability of resource etc. of uPUSCH transmission) determine TBS zoom factor.For example, available in other resource In the case where uPUSCH transmission (for example, in the case where other resource obtains the resource of one or more threshold numbers), TBS determines that component 1214 can choose biggish zoom factor.Similarly, if less resource can be used for uPUSCH transmission (for example, in the case where less resource is less than the resource of one or more threshold numbers), then can choose lesser scaling The factor.It should be appreciated that receiving uplink resource allowance at box 1302 can also include: reception and grant of resources Associated other parameters, for example, start offset, bandwidth of distribution etc. can determine that uplink provides according to these parameters The size of one or more RB groups in the allowance of source.

At box 1308, UE can be permitted based on uplink resource, determine transmitting in subframe for uplink TTI.In one aspect, which includes at least one symbol, one or more symbols, time slot etc..On the other hand, The TTI includes one or more symbols, wherein one or more of symbols are the subsets of multiple symbols in subframe.TTI is true The use in subframe can be determined based on by the allowance of the received uplink resource of grant of resources receiving unit 1210 by determining component 1212 In the TTI of uplink transmission.As described above, continuing about ULL frame structure 800,900 for example, TTI can be a symbol Time, multiple symbol durations, time-slot duration etc., wherein LTE subframe includes 12 or 14 symbols according to CP.TTI Determine that component 1212 can be based at least partially on from the received configuration of eNB 1204, from the received grant of resources of eNB 1204 Information (for example, instruction of the resource of the allowance in second stage grant of resources) etc., determine for uplink transmission TTI。

At box 1310, UE can during the TTI, by uplink resource is permitted specify resource, to Network entity sends communication.For example, in one aspect, as described, communication component 661 can be during the TTI, by upper The resource specified in downlink resources allowance sends communication (for example, ULL is communicated to network entity (for example, eNB 1204) 1282), wherein the TTI can less than one subframe on the duration.As described, send communication may include: one or Multiple processors 1203 provide data and/or related signal message to transceiver 1206, to be led to via the front end RF with generating Cross the signal etc. that one or more antennas are sent.Due to the TTI of shortening, for example, interference may span across TTI (for example, across More symbol) variation, and therefore may expect for ULL communicate, according to TTI grades (for example, according to symbol level, two symbol levels, when Gap grade etc.) it is eliminated to execute interference.In this regard, in one example, sending communication at box 1310 can Selection of land perforates to one or more symbols using the symbol of one or more configuration, at box 1312 to help to do Disturb elimination.For example, perforation may refer to: once generating symbol according to data to be sent, just being matched using one or more The symbol set replaces one or more of symbols.Communication component 661 can use the symbol of one or more configurations to one A or multiple symbols are perforated, to provide the symbols of one or more perforation, with facilitate to network entity (for example, ENB 1204) send communication when interference eliminate.One or more of symbols to be perforated may be at known location, example Such as, allow eNB 1204 observe such as the symbol of one or more configurations of known location middle punch (for example, these In the case where knowing that position is configured at UE 1202 and/or eNB 1204).

For example, in communication component 661 (for example, in processor corresponding with transceiver 1206) to perforated symbol Before DFT is executed to generate the signal being used for transmission, perforated symbol may include perforated one of (for example, replacement) or The symbol of multiple encoded/modulation.In addition, for example, the symbol configured can be (for example, be stored in UE 1202 (and/ Or eNB 1204) at configuration in, from eNB 1204 receive etc.) with the value as known to UE 1202 and eNB 1204 symbol Number.Therefore, the symbol of subsequent known configurations can correspondingly allow eNB to identify in the transmission from UE 1202 to be configured Symbol, and the given value that configured symbol can be used is estimated the symbol together with the received transmission of institute, successive character, is somebody's turn to do Interference on one or more symbols of subframe etc..In this regard, symbol is carried out using known, configuration symbol Perforation, can retain the SC-FDM attribute for the signal to send from UE 1202 to eNB 1204.In addition, perforated symbol can To have order of modulation more lower than order of modulation corresponding with uplink resource allowance.

Further, since UE 1202 may be operable such that with ULL and other RAT (for example, traditional nothing of such as LTE etc Line communication technology) it is communicated, therefore optionally at box 1314, UE can be based on the 2nd TTI with sub-frame duration Related other communications, to send communication.In one aspect, other communications can also be dispatched on the TTI.For example, at one Aspect, communication component 661 other can be communicated (for example, LTE communication based on related with the 2nd TTI of sub-frame duration 1282) (for example, ULL communication 1282), is communicated to send, wherein also dispatching other communications on the TTI (for example, ULL TTI). As described, sending communication as described, to may include: one or more of processors 1203 provide number to transceiver 1206 According to and/or related signal message, with generate will be via front end RF etc., the letter sent by one or more antennas Number.In other words, " communication " can be any ULL communication, and " other communications " to can be the TTI different from ULL TTI related Any communication, the TTI are such as, but not limited to: the TTI specified in traditional LTE communication, related to other communications in other RAT TTI of connection etc..Therefore, in one aspect, communication component 661 can handle same time interval (for example, subframe or its A part) in, (for example, on ULL) these communicates and (for example, in the traditional wireless communication technology of such as LTE etc ) potential conflict between the concurrent transmission of the scheduling of other communications.

For example, can be optionally included based on other communications to send the communication at box 1314: in box 1316 Place sends the communication and other communications simultaneously during the TTI.For example, in one aspect, communication component 661 can be same When during the TTI, send it is described communication and other boths.This may include: that one or more processors 1203 are raw At for providing the signal to be transmitted to transceiver 1206, wherein these signals may include in opposite with these signals The communication and other communications in similar frequency and/or time resource answered.For example, this may include: that communication component 661 is logical Cross respective resource send it is described communication and other communications, wherein be assigned to it is described communication and other communications RB and/or RB group do not conflict (but it is described communication and other communications may be weighed in the time domain in one or more subframes or part of it It is folded).In another example, communication component 661 can simultaneously send the communication and other communications, wherein by that will come from The control information of other communications include (for example, bearing) in ULL communication (for example, by from the control of PUCCH or PUSCH letter Breath is born on uPUSCH transmission etc.), to make other communications including controlling information.

For example, with reference to Fig. 8 and Fig. 9, it is this bear may include: communication component 661 in the domain PUCCH 802 (and/or In the domain PUSCH 806, according to the frame structure for being configured for ULL communication), the control information of other communications is sent, and in the domain ULL Transmission ULL communication in (for example, the domain uPUSCH 810 and/or domain uPUCCH 808).PUCCH communication may include such as ACK/ The uplink control instructions of NACK, scheduling request (SR), CSI etc. accord with (UCI).But in another example, lead to Letter component 661 in domain 804, can send the control information of other communications.

In another example, the communication is sent at box 1314 to be made described optionally at box 1318 Communication is prior to other communications.Communication order of priority partitioning component 1216 can make the communication (for example, ULL is communicated) described Prior to other communications (for example, LTE communication) in TTI.For example, from the received one or more uplink resources of eNB 1204 Dispatching communication is permitted may cause in similar resource (for example, in these Energy Resources Service, these TTI overlapping) (for example, ULL is logical Letter) and other communications (for example, LTE communication), herein referred to as conflict or conflicted resource.For example, ULL communication can be in symbol It is scheduled in TTI, wherein the symbol is located in the subframe TTI for dispatching other communications on it.In this regard, in box At 1318 to communication divide order of priority may include: communication order of priority partitioning component 1216 be used in other communications Transmitting the ULL communication transmitted in equitant resource has priority, and communication order of priority partitioning component 1216 makes ULL When communication has priority, other communications in entire TTI (for example, LTE subframe) are abandoned, wherein ULL communication may occur In subsequent TTI in the burst etc..This can retain for the single carrier waveform for sending the signal that ULL communication generates, It is at least in the case that link is limited in UE 1202 may be beneficial, because low PAPR is presented in single-carrier signal.Above Make the communication prior in the example of other communications, the communication can be related to the communication of the uPUCCH in ULL, uPUSCH leads to Letter, uRS communication etc. and/or other communications can be related to the communication of the PUCCH in LTE, PUSCH communication, SRS communication etc..

But in the case where making ULL communication prior to PUCCH LTE communication, for example, since time domain expands on RB, So the PUCCH format (for example, format 1,1a, 1b, 2a, 2b, 3 etc.) based on the current regulations in LTE, abandons one or more A PUCCH symbol may cause the nonorthogonality with other PUCCH of same RB.Thus, for example, it is preferential to have ULL communication Grade may include: that communication component 661 is sent out using new defined format (except the PUCCH format of its current regulations in LTE) Other communications (for example, the PUCCH in LTE is communicated) are sent, wherein time domain does not expand on RB these new defined formats, Huo Zhe Otherwise allowable clearance when time domain extends.In another example, it is communicated in equitant RB based on determining with other ULL communication is sent, communication component 661 can send other communications in the RB different from RB used in ULL communication is sent.

Additionally or in alternative solution, for example, the communication is sent based on other communications at 1314, it can be optional Ground makes other communications prior to the communication at box 1320.In some instances, order of priority partitioning component 1216 is communicated Other communications (for example, LTE communication) can be made prior to the communication (for example, ULL is communicated).For example, it is other communication with compared with In high-level signaling (for example, RRC signaling, signaling such as related with the RRC of eNB 1204 connection) corresponding situation, communicate excellent First order partitioning component 1216 can make other communications have priority, so that ULL communication is not in initial scheduling (for example, conflict) It is sent in the subframe or part of it of the communication and other boths.

In another example, money when sending communication at box 1310, for uPUSCH and uRS communication in ULL Source may be conflict (for example, the case where grant of resources receiving unit 1210 receives the grant of resources that there is uRS to trigger Under).It gives one example, when there are such conflict, communication component 661 can send uPUSCH during the TTI, without Send uRS.In another example, communication component 661 can simultaneously send both uPUSCH and uRS during the TTI.? In this case, communication component 661 can send the two channels, allow these channels same by occupying during the TTI Different resource in one bandwidth, to share same bandwidth.

In another example, the resource for uPUCCH and uRS communication in ULL may conflict during the TTI. It gives one example, when there are such conflict, communication component 661 can send uPUCCH during the TTI, rather than uRS.In another example, communication component 661 can simultaneously send both uPUCCH and uRS during the TTI.At this In the case of, communication component 661 can send the two channels, allow these channels by occupying same during the TTI Different resource in bandwidth, to share same bandwidth.

In another example, as described above, communication component 661 can answer one or more symbols and modulation symbol collection With to facilitate the channel estimation or Interference Estimation on TTI.It gives one example, which can have predetermined Value (it includes zero), wherein these predetermined values may be known for eNB 1204 or other network entities. In another example, which can have modulation order more lower than order of modulation corresponding with grant of resources Number, to facilitate based on the lower order of modulation compared with the corresponding remaining symbol of grant of resources, to identify these modulation symbols Number.

Figure 14 shows less than the duration of basic conventional communication techniques (for example, being less than the son in LTE based on having Frame) duration TTI, (for example, by eNB 1204) scheduling for one or more UE uplink communication example Property method 1400.At box 1402, eNB can be based on including one or more symbols, time slot etc., (they can be subframe In multiple symbols subset) TTI, generate for UE uplink resource permit with dispatch be directed to the UE uplink Communication.For example, in one aspect, as described, grant of resources formation component 1220 can be based on including one or more symbols The TTI of (they are the subsets of multiple symbols in subframe), the uplink resource generated for UE 1202 are permitted to dispatch needle To the uplink communication of UE 1202.For example, grant of resources formation component 1220 can based on a such as symbol or The TTI of the duration of two or more symbols of person or a time slot etc. generates uplink resource and permits being used for ULL Communication.In addition, as described, it is being one that grant of resources formation component 1220, which can be generated to include by one or more RB groups, Uplink resource in the TTI that control or sub-data transmission on a or multiple uplink channels are matched is permitted.Lift an example Son, ULL grant of resources can be provided according to ULL frame structure 800 (Fig. 8) described above and/or 900 (Fig. 9).In addition, such as Description, grant of resources formation component 1220 can be based on the system bandwidth that can be used for permitting on the TTI to UE 1202 Amount generates the uplink resource to include similarly sized multiple RB groups and permits.

At box 1404, eNB, which can transmit uplink resource to UE, to be permitted.For example, in one aspect, dispatching component 602 can transmit uplink resource to UE permits (for example, uplink resource permits 1280).As described, which can To include: one or more processors 1253 to the offer data of transceiver 1256 and/or related signal message, it is used for generating The signal etc. sent via the front end RF by one or more antennas.For example, scheduling component 602 can be at one or more (for example, PDCCH or uPDCCH etc.) transmits uplink resource allowance in down link signal on a downlink channel, As described, grant of resources receiving unit 1210 to obtain uplink resource to permit (for example, via transceiver 1206), and (for example, via transceiver 1206) can be communicated in the resource that indicate in uplink resource allowance, such as Description.Therefore, at box 1406, eNB can be permitted based on uplink resource, during TTI, receive uplink from UE Road communication.Dispatching component 602 can be permitted based on uplink resource, and during TTI, it is logical to receive uplink from UE 1202 Letter (for example, ULL/LTE communication 1282).As described, receiving communication may include: that transceiver 1256 receives one or more letters Number (for example, via the front end RF), and the information about these signals is provided to one or more of processors 1253, with right These signals are decoded, demodulate or processing otherwise, to obtain data therein.

In addition, for example, transmitted at box 1404 uplink resource permit can optionally at box 1408, Permit to the UE transmission multistage.For example, in one aspect, grant of resources formation component 1220 can permit uplink resource It is generated as multistage allowance, and dispatch component 602 to transmit multistage allowance to UE 1202.Thus, for example, one Or multiple signals for sending multistage allowance can be generated in multiple processors 1253, and transceiver 1256 can be via RF Front end sends the multiple signal with one or more antennas.As described, which permits may include the first stage Grant of resources and/or second stage grant of resources, wherein first stage grant of resources may include permitting for uplink MCS, the TPC for the uplink communication from UE 1202, and/or precoding information etc., second stage grant of resources can To include NDI, increment MCS, RS circulation, RS triggering, non-periodically CSI triggering, the instruction of resource permitted etc..

In addition, for example, transmitted at box 1404 uplink resource permit can optionally at box 1410, The one or more parameters permitted about uplink resource are transmitted to UE.For example, in one aspect, scheduling component 602 can be with The one or more parameters permitted about uplink resource are transmitted to UE 1202.It gives one example, grant of resources formation component 1220 uplink resources that can be generated to include one or more of parameters are permitted.For example, grant of resources generation group Part 1220 can specify start offset and/or system bandwidth in grant of resources, to be designated as one or more uplink letters The size of one or more RB groups in the TTI that control or sub-data transmission on road are matched.In another example, grant of resources Formation component 1220 can be based on the size that uplink resource is permitted (for example, the size based on one or more of RB groups And/or quantity), the TBS zoom factor in specific uplink grant of resources.Due to what is distributed in uplink resource is permitted Bandwidth is configurable, therefore TBS zoom factor can be with scaling of the indicator to the bandwidth distributed, to realize certain TBS.

Optionally, at box 1412, eNB can be based at least partially on received one in uplink communication Or multiple modulation symbols are compared with the modulation symbol of one group of configuration, to execute at least one in channel estimation or Interference Estimation It is a.For example, in one aspect, channel/interference estimated component 1222 can be based at least partially on will be in uplink communication Received one or more modulation symbol is compared with the modulation symbol that the group configures, to execute channel estimation or Interference Estimation At least one of.As described above, UE 1202 can use the modulation symbol of one or more configurations in uplink communication One or more symbols perforate, wherein these configuration modulation symbols can be in UE 1202 and eNB 1204 The configuration of each place, configured from eNB 1204 to UE 1202 etc. so that UE 1202 and eNB 1204 know these symbols, Position of these symbols etc..In this regard, for example, channel/interference estimated component 1222 can be logical for uplink Letter perforated symbol, observation such as in known location received symbol, and can by perforated symbol with it is known The symbol of one or more configuration is compared, to determine channel associated with uplink communication and/or interference.In addition, It is lower that perforated symbol can have order of modulation more corresponding than communication in the resource permitted with uplink resource Order of modulation, as described, to facilitate detection and/or its more reliable transmission.

Optionally, in addition, at box 1414, eNB can be based on the 2nd TTI, generate and be directed to the UE or one or more The second uplink resource of other UE is permitted, and is communicated with scheduling uplink.For example, in one aspect, grant of resources generates Component 1220 can be based on the 2nd TTI, generate the second uplink resource for being directed to UE 1202 or one or more of the other UE Permit, is communicated with scheduling uplink.As described, eNB 1204 may be able to use ULL communication and some other communication (example Such as, the basic conventional communication techniques of such as LTE etc) it is communicated.Therefore, grant of resources formation component 1220 can be based on holding The continuous time is the TTI (as in LTE) of subframe, generates the second uplink for being directed to UE1202 or one or more of the other UE Road grant of resources.In this example embodiment, eNB 1204 can support ULL communication and LTE communication.

Optionally, in addition, at box 1416, eNB can be to the UE or one or more of other UE transmission Second uplink resource is permitted, and/or at box 1418, eNB can be during the 2nd TTI, from the UE or described One or more of the other UE receives other uplink communication.For example, in one aspect, scheduling component 602 can be by receiving In one or more down link signals 1209 that hair machine 1206 is sent, to UE 1202 or one or more of other UE The allowance of the second uplink resource is transmitted, and/or can be during the 2nd TTI in the one or more sent by UE 1202 Other uplink communication is received in downlink signal 1208, for example, coming from UE 1202 or one or more of other Other communications of the basic conventional communication techniques (for example, LTE) of UE, wherein the 2nd TTI can receive it at box 1406 On the TTI of uplink communication overlap.

Figure 15 is shown for determining the exemplary side for wanting (for example, by UE 1202) to send RS based on received triggering Method 1500.At box 1502, UE, which can receive uplink resource from network entity, to be permitted, and wherein the uplink resource is quasi- Permitted to include: the indicator that send for uplink control or the DM-RS for data channel.For example, a side Face, grant of resources receiving unit 1210 can receive uplink resource from network entity (for example, eNB 1204) and permit (example Such as, uplink resource permit 1280), wherein the uplink resource allowance include: be to send for uplink control Or the indicator of the DM-RS for data channel.As described, for example, reception uplink resource is permitted and indicator can To include: via transceiver 1206, the uplink resource received in one or more down link signals 1209 is permitted and is referred to Show symbol, and signal 1209 is handled by one or more processors 1203, to obtain specific to the uplink resource The information of allowance and/or indicator.For example, the DM-RS can correspond to the uRS for communicating description above for ULL.With regard to this point For, the grant of resources for UE 1202 can be generated in grant of resources formation component 1220, may include whether to send The indicator of DM-RS (it is generated by RS trigger assembly 1224), and dispatch component 602 can to UE 1202 send should Grant of resources, to be received by grant of resources receiving unit 1210 via communication component 661.

At box 1504, UE can be based at least partially on the indicator, it is determined whether send out at least one TTI Send DM-RS.RS triggering receiving unit 1218 can be based at least partially on the indicator, it is determined whether be at least one TTI Middle transmission DM-RS.For example, RS triggering receiving unit 1218 can determine will be at least one if receiving the indicator DM-RS (for example, uRS) is sent in TTI.In addition, as described above, RS triggering receiving unit 1218 can (it can based on RS triggering Be the multistage permit in it is received), determine in the TTI that wherein send DM-RS.For example, the grant of resources may include: For sending the explicit instruction (for example, TTI index or other identifiers in subframe) of the TTI of DM-RS, the implicit finger of TTI Show (for example, instruction of the quantity of the TTI after receiving the TTI of grant of resources on it) etc..

Optionally, at box 1506, UE can receive in one or more TTI send DM-RS it is one related Or multiple parameters.For example, in one aspect, RS triggering receiving unit 1218 can receive to be sent in one or more TTI The related one or more parameters of DM-RS.For example, RS trigger assembly 1224 can send (example to UE 1202 with signal form Such as, via transceiver 1256, sent in one or more down link signals 1209) one or more parameter, for example, In RRC or other configurations.In another example, RS trigger assembly 1224 can be in multistage grant of resources etc., with letter Number form sends one or more of parameters to UE 1202.Anyway, it gives one example, RS triggers receiving unit 1218 It can be based on configuration be received, to determine one or more of parameters.One or more of parameters for sending DM-RS can To include: one or more cyclic parameters of periodic transmission for DM-RS, the bandwidth for sending DM-RS, on it exist Sent in the TTI (for example, symbol) of configuration DM-RS one or more frequency locations, on the TTI of multiple configurations not The quantity of the Hopping Pattern, antenna port for being used when sending DM-RS that are used when sending DM-RS in same frequency position, Pectination for using when sending DM-RS is horizontal (for example, as tradition SRS sign convention).In another example In son, RS triggering receiving unit 1218 can be determined based on received similar parameter is transmitted for uPUCCH and/or uPUSCH One or more of parameters.

For regular uRS transmission, for example, at least one subset of one or more of parameters can be with regular RS Trigger it is related, for example, periodically (for example, the instruction of the unit of TTI, millisecond (ms) or be used to indicate will on it regularly Send the other parameters of the TTI of uRS).One or more of parameters may further specify that periodicity, so that some in subframe URS (for example, every N sub-frames, wherein N can be positive integer) is sent in TTI set.In another example, one or Multiple parameters may include: by the instruction (for example, quantity of resource block) for the bandwidth for sending uRS on it.It gives one example, band Wide instruction may include the integral multiple of 4 resource blocks.In another example, one or more of parameters can be with regulation Hopping Pattern for uRS is related, wherein the resource that be used to send uRS can be jumped from a frequency location in a TTI Change to another frequency location (for example, based on the parameter or other way) in another TTI.Thus, for example, described one A or multiple parameters may include: the frequency between the instruction or one or more TTI of the frequency location for prescribed model Instruction at interval between resource etc..In addition, for example, one or more of parameters may include: for when sending uRS The instruction of the quantity of the antenna port used.For example, in the case where uRS is related to uPUCCH transmission (and for example, it is such as Sent in the domain uPUCCH 808 shown in Figure 11), the quantity of antenna port can be fixed on one.It is related in uRS In the case where uPUSCH transmission (and it is sent in the domain uPUSCH 810 as shown in Figure 11), in conjunction on uPUSCH Possible UL MIMO operation, the quantity of antenna port can be one, two, four etc..In addition, each antenna port It can be non-precoded, and/or 1 port SRS can be similar to.In addition, one or more of parameters can be each day Line end mouth assigns different cyclic shift or pectination offset.For example, when non-periodically uRS is unavailable, regular uRS can by with Demodulated in uPUCCH and/or uPUSCH, or when non-periodically uRS is available, can come in conjunction with non-periodically uRS using.Regular uRS May be utilized for assisting the scheduling based on uplink subband, especially in different transmission, using frequency hopping come When realizing uRS.Regular uRS can also be provided according to up-link power control, uplink temporal/frequency-tracking etc. " keep-alive " UL operation.

For non-periodically uRS, non-periodically RS can be triggered and be specified to be related to: the TTI (example based on timing relationship Such as, 3 TTI after the triggering), and/or some periodic TTI is based additionally on (for example, the instruction of the unit of TTI, milli Second (ms) or be used to indicate will regularly send the other parameters of the TTI of uRS on it).One or more of parameters are also It can specify that periodicity, so that uRS may be sent in the assemble of symbol of some in subframe (for example, every N sub-frames, wherein N can To be positive integer).For example, if one or more of parameters are related to being sent in the non-periodically uRS triggered in symbol n, Wherein n can be positive integer, if symbol n+3 is not configured for the symbol of non-periodically uRS transmission, and symbol n+4 is matched It is set to the symbol for non-periodically uRS transmission, then communication component 661 can alternatively send non-periodically uRS in symbol n+4. As described in about regular uRS, one or more of parameters may include: to send the bandwidth of uRS on it.Once by touching Hair then can only send non-periodically uRS primary (single transmission) or send repeatedly (being transmitted several times).Assuming that multiple non-periodically URS can enable jump (for example, and configuring associated Hopping Pattern parameter), allow uRS from one transmission in one A frequency location jumps to another frequency location in another transmission.Non-periodically uRS can also be configured with mutiple antennas Port, as about regular uRS described in similar (for example, making the non-periodically uRS for uPUCCH that an antenna end can be used Mouthful, and/or 1,2,4 etc. antenna ports can be used in uRS for uPUSCH).As described above, in this example embodiment, each Antenna port can be non-precoded, and/or can be similar to 1 port SRS.In addition, one or more of parameters can be with Different cyclic shift or pectination offset are assigned for each antenna port.Non-periodically uRS can individually be used for uPUCCH And/or uPUSCH demodulation, or regular uRS is combined to use (when regular uRS is available).When there are adjoint uPUCCH or When uPUSCH, uRS parameter can be consistent, or based on uPUCCH or uPUSCH parameter.For example, uRS can have Bandwidth identical with corresponding uPUSCH, the quantity of frequency location and antenna port.When there is no adjoint uPUCCH or When uPUSCH, for example, uRS parameter can be based on some dynamic instruction in uplink resource allowance.

In any case, optionally, at box 1508, UE can will send DM-RS based on determination, send out in TTI Send DM-RS.For example, in one aspect, to send DM-RS, communication component in TTI based on RS triggering 1218 determination of receiving unit 661 can send DM-RS (for example, such as ULL/LTE communication 1282) in TTI.Therefore, sending DM-RS in TTI can Selection of land includes: at box 1510, and the parameter that configures based on one or more sends DM-RS.As described above, it is one or The parameter of multiple configurations can correspond to trigger one or more parameters that receiving unit 1218 is received or determined by RS, so as to Regular and/or non-periodically DM-RS (for example, uRS) is sent in one or more TTI.As described, sending RS may include: Corresponding signal can be generated in one or more processors 1203, via the front end RF, to pass through one by transceiver 1206 Or mutiple antennas transmitted in the case where (for example, using specified frequency location (it can be based on Hopping Pattern), make With the antenna port of specified quantity or pectination level etc.), communication component 661 sends DM- in one or more of TTI RS.It gives one example, as shown in time shaft 1000,1010 above, the DM-RS that is sent by communication component 661 (for example, URS it) can take up a symbol.In addition, for example, each DM-RS can have configurable bandwidth, configurable jump mould Formula jumps DM-RS (for example, it can be true by eNB 1204 across subband, different pectination offsets etc. It is fixed, and via for specifying the RS trigger assembly 1224 of one or more parameters to control to UE 1202).In addition, each DM-RS can have non-precoding and/or can indicating via the cyclic shift of one or more of ports is indicated One or more ports.The cyclic shift can be configured by RS trigger assembly 1224, and be assigned to UE 1202 (for example, making For a part or other way of grant of resources).

For example, communication component 661 can be based on from the received one or more parameters of eNB 1204, and transmission passes through (for example, in downlink control instructions symbol (DCI)) receives the non-periodically uRS that uplink resource is permitted and triggered.Example Such as, communication component 661 can send uRS, so that this is periodically with corresponding uPUSCH difference (for example, receiving uplink 3 TTI after allowance send uRS, and wherein uPUSCH is that 4 TTI after uplink allowance are sent, such as Figure 10 Shown in time shaft 1010).In another example, communication component 661 can be sent based on one or more of parameters The regular uRS of triggering, wherein one or more of parameters can identify the explicit TTI for sending uRS (for example, at 6 Followed by 9 TTI of TTI, as shown in the time shaft 1000 of Figure 10).In addition, for example, communication component 661 can divide Not in frequency location associated with control and data communication, send for uRS in each of control and data communication, such as (for example, uPUSCH uRS in the domain uPUCCH uRS and uPUSCH 810 in the domain uPUCCH 808) shown in Figure 11.

Optionally, at box 1512, UE can be based at least partially on grant of resources, identical as DM-RS or not In same TTI, at least one of control channel or data channel are sent.For example, in one aspect, communication component 661 can be with It is based at least partially on (for example, received from eNB 1204) grant of resources, in the TTI same or different with DM-RS, hair Send at least one of control channel or data channel.As above in Figure 13 it is similar described in, control channel or data channel It can correspond to PUCCH, PUSCH, SRS etc. in LTE, and in the case where not allowing parallel transmission, DM-RS can be made Transmission have priority；Therefore, in this example embodiment, at least one control channel is sent at box 1512 or data channel can To include: to send at least one control channel or data channel in the TTI different from DM-RS.In another example, it controls Channel or data channel processed can correspond to uPUCCH or uPUSCH, and uRS can be sent in combination with them, can also be with It does not send in combination；Therefore, in this example embodiment, as described above, sending at least one control channel or data at box 1512 Channel may include: to send at least one control channel or data channel in the TTI identical or different with uRS.

For example, UE 1202 can make uRS prior to PUSCH in the case where uRS conflicts with the PUSCH transmission in LTE Transmission, so that the PUSCH that communication component 661 can abandon in conflict symbol is passed in the conflict symbol for sending uRS and PUSCH It is defeated, and/or the entire TTI for PUSCH can be abandoned.Similarly, communication component 661 can abandon and uRS transmission collision SRS transmission in symbol.In addition, as described in above for the conflict between the PUCCH in ULL communication and LTE, it usually can be with Make uRS prior to PUCCH, communication component 661 is allowed to abandon the PUCCH transmission in conflict symbol, and/or use can be abandoned In the entire TTI of PUCCH, but in some cases, it can make PUCCH that there is priority, so that the uRS transmission in conflict symbol It is dropped (for example, communicating in situation corresponding with rrc layer communication in PUCCH).In addition, such as logical above for the ULL of conflict What letter and PUCCH communication described, in the PUCCH format based on current regulations, the one or more symbols for abandoning PUCCH may be made At with other PUCCH it is non-orthogonal in the case where, can specify that other PUCCH format to allow communication component 661 to put PUCCH It sets in different RB.

Figure 16 is shown for whether (for example, from eNB 1204) transmission will to send DM-RS to UE (for example, UE 1202) Indicator illustrative methods 1600.At box 1602, uplink resource allowance is can be generated in eNB, wherein the uplink It is to send for the DM-RS of uplink control or believe for data that it includes: at least one TTI that link circuit resource, which is permitted, The indicator of the DM-RS in road.Uplink resource allowance can be generated in grant of resources formation component 1220, wherein the uplink Grant of resources, which includes: at least one TTI, to be sent for uplink control or for the DM-RS of data channel Indicator.For example, RS trigger assembly 1224 can to grant of resources formation component 1220 indicate for send DM-RS (for example, URS triggering), to help to generate grant of resources using the triggering for sending DM-RS.Generate at box 1602 includes referring to One or more parameters can be included related with DM-RS transmission at box 1604 by the uplink resource allowance for showing symbol Uplink resource permit in.One or more parameters can be included providing in uplink by grant of resources formation component 1220 During source is permitted, wherein these parameters are related with DM-RS transmission.As described, one or more of parameters can determine with sending Phase or non-periodically DM-RS are related, and may include one or more of the following items: sending DM-RS's during it The explicit or implicit instruction of TTI, cyclic shift, bandwidth, Hopping Pattern, one or more frequency locations, one or more antennas Port, one or more pectination levels etc., use for UE 1202 when sending DM-RS.

At box 1606, eNB can send uplink resource allowance and indicator to UE.Dispatching component 602 can be with Uplink resource, which is sent, to UE permits (for example, uplink resource permits 1280) and indicator.For example, scheduling component 602 It can permit in (for example, as described above, the RS in such as second stage is triggered) in RRC signaling, in the multistage, to UE 1202 transmission uplink resources are permitted.As described, scheduling component 602 can be based on mentioning to one or more processors 1253 For data related with the allowance and indicator, to generate signal message and provide the signal message to transceiver 1256, to send out Downlink resources allowance and indicator are served, wherein the generation of transceiver 1256 is used to indicate one of the allowance and/or indicator Or multiple signals, and via the front end RF, it is sent by one or more antennas.As described, grant of resources receives Component 1210 and/or RS triggering receiving unit 1218 can receive uplink resource allowance and/or indicator.Such as description , uplink resource allowance can correspond to based on ULL TTI come granted resources, for send uplink control with/ Or data and for sending uRS.

Optionally, at box 1608, eNB can receive one or more DM-RS from UE at least one TTI.It adjusts Degree component 602 can receive one or more DM-RS from UE 1202 at least one TTI.For example, component is dispatched 602 can correspondingly use the DM- when received communication demodulates in the respective resources executed to uplink resource RS.It may include: to be based at least partially on described one at box 1610 that one or more DM-RS is received at box 1608 A or multiple parameters receive one or more of DM-RS (for example, as ULL/LTE communication 1282).Therefore, as described, These parameters can explicitly or implicitly indicate that UE 1202 will send on it at least one TTI of DM-RS, and dispatch Component 602 can receive DM-RS at least one described TTI.Similarly, scheduling component 602 can be one or more In a parameter specify bandwidth on, according to the Hopping Pattern or frequency location, via the antenna port of the quantity, according to comb Shape level etc., to receive DM-RS.It gives one example, scheduling component 602 can receive independent with data communication for controlling URS, wherein these uRS may each be respectively received with control and the related frequency resource of data communication, such as Figure 11 Shown in.

Figure 17 shows the illustrative methods for sending uplink control data in ULL (for example, by UE 1202) 1700.At box 1702, UE can determine the TTI for uplink control channel transmission in subframe.In one aspect, The TTI includes a symbol, multiple symbols, time slot etc., they are the subsets of multiple symbols in subframe.TTI determines component 1212 can determine the TTI for uplink control channel transmission in subframe.It gives one example, as described, this can be with It is to be based on by grant of resources receiving unit 1210 from the received grant of resources of eNB 1204 (for example, uplink resource is permitted 1280), it can indicate TTI duration, the type (for example, ULL) of the communication technology etc..In addition, for example, as described , which can have a symbol duration, multiple symbol durations, time-slot duration etc..

Optionally, at box 1704, UE can be based on RB associated with downlink control channel or data channel Group index, to determine the resource location for sending control data.Communication component 661 can be based on and downlink control channel Or the associated RB group index of data channel, to determine the resource location for sending control data.For example, communication component 661 Downlink control and/or data channel communication can be received from eNB 1204, as described, and can be received based on institute Communication, determines the resource location for sending the control data of downlink control and/or data channel.For example, communication component 661 can determine the resource location with reception downlink control channel and/or data channel on it but in subsequent TTI RB group index is identical, it is determining there is with the RB group index some offset resource location (for example, here, the offset can be by Grant of resources receiving unit 1210 is received in grant of resources) etc..

Optionally, at box 1706, UE can determine the quantity of the RB for uplink control channel.Communication component 661 can determine the quantity of the RB for uplink control channel.For example, communication component 661 can be based at least partially on (for example, instruction based on the resource distributed by the grant of resources) is permitted from the received uplink resource of eNB 1204, is determined The quantity of RB for uplink control channel.In another example, communication component 661 can be based at least partially on really The payload size of fixed control data to be sent determines the quantity of the RB for uplink control channel (for example, really Determine the byte-sized of payload, MCS and/or may achievable handling capacity related with the MCS etc.).

At box 1708, UE can send uplink on uplink control channel and control number during TTI According to.Communication component 661 can send uplink control data (for example, such as during TTI on uplink control channel 1282) ULL/LTE is communicated.As described, grant of resources uplink control channel can be sent based on the received, wherein connect Uplink control channel resource on the grant of resources instruction TTI of receipts, wherein the uplink control channel resource includes being somebody's turn to do One or more RB RB groups in TTI.Communication component 661 can be additionally based on identified resource location (for example, being based on The RB group index of the control of related downlink or data channel), identified RB quantity etc., scheduling and send control number According to.The control data may include the ACK/ for received data in the downlink channel in TTI, SR etc. previous NACK feedback, and communication component 661 can additionally be used for the transmission using different signalings.As described, in transmission Line link control data, which may include: one or more processors 1203, provides data and/or related letter to transceiver 1206 Number information, to generate for via front end RF etc., the signal sent by one or more antennas.

For example, in the case where uplink control data is related to the SR to send in uplink control channel, money Formation component 1220 is permitted in source can be generated the associated grant of resources for UE 1202, specify for sending in ULL The resource (for example, RB and/or cyclic shift) of the RRC configuration of SR.Grant of resources receiving unit 1210 can receive resource standard Perhaps, and communication component 661 can be based on the resource (for example, using these RB and/or corresponding cyclic shift) configured, phase SR is sent to eNB 1204 with answering.It for example, may include: the explicit of RB by the RB that grant of resources formation component 1220 indicates Indicate, since with it is corresponding control or the corresponding RB of RB group index of data channel the quantity of RB or corresponding with this The quantity of RB etc. of the RB group index of control or data channel offset.

In another example, at box 1708, UE can be optionally at box 1710, not using one or more With cyclic shift send control data, to indicate one or more values of control data.Institute can be used in communication component 661 One or more cyclic shifts are stated to send control data, to indicate one or more values of control data.For example, only In the case that ACK/NACK will be sent in uplink control channel, grant of resources formation component 1220 be can be generated for UE 1202 grant of resources for being sent on PUCCH.Grant of resources receiving unit 1210 can receive the grant of resources, And communication component 661 can be based at least partially on from the block of the received corresponding uPDCCH data of eNB 1204 and index, phase ACK/NACK is sent to eNB 1204 on PUCCH with answering.Grant of resources formation component 1220 can specify for ACK and NACK Different cyclic shifts, wherein communication component 661 can use these cyclic shifts when sending ACK and NACK.For example, circulation Displacement 0 can be used for ACK, and cyclic shift 6 can be used for NACK.In addition, for example, grant of resources formation component 1220 can (for example, in grant of resources) specify the different cyclic shifts of the combination of transmitted for SR and ACK or NACK, wherein Communication component 661 can use these cyclic shifts when sending SR and ACK or NACK.For example, cyclic shift 2 can be used for ACK and SR certainly, and cyclic shift 8 can be used for NACK and SR certainly.

In addition, UE can also substitute RS optionally at box 1712 to send control data at box 1708, or Person will control data and send together with RS.Communication component 661 can substitute RS to send control data, or will control data It is sent together with RS.For example, grant of resources may include RS triggering (for example, being used to determine when to send uRS).URS's In the case where the transmission collision of transmission and control data, as previously described, communication component 661 can be determined that substitution uRS comes Control data are sent, or control data are sent together with uRS.For example, in uRS and uplink control channel uPUCCH Transmission collision in the case where, communication component 661 can send uPUCCH and abandon uRS, send uRS and abandon uPUCCH (example Both such as, it is in optional situation that uplink control data is sent at box 1708), or can send.For example, in order to Both send, if its be SR perhaps if ACK/NACK communication component 661 can by send have be used to indicate SR or The uRS of the different cyclic shifts of ACK/NACK, to send uPUCCH.If by both SR and ACK/NACK together with uRS If scheduling, then in this example, SR can be abandoned.

In addition, for example, and at box 1714, UE can in multiple code words or multiple carrier waves extremely Few one ACK/NACK is bundled, to be sent on uplink control channel.Communication component 661 can be to being used for At least one of multiple code words (they can be over a number of carriers (for example, in MIMO communication or carrier wave polymerization)) ACK/NACK is bundled, to be sent on uplink control channel.For example, carrying out binding to ACK/NACK can wrap Include: specify for the multiple code word or carrier wave single ACK/NACK value (for example, if all values are all ACK, for ACK, and if at least one value is NACK, for NACK etc.).Binding can also include: the sky of ACK/NACK value Between bundle.

In another example, uplink control data is sent at box 1708 may include: by uplink control Data processed are used as two or more ACK/NACK ratios in each of two or more code words and/or one or more carrier waves Spy sends.In addition, for example, the space binding in carrier wave may be implemented, allow to generate N number of for N number of carrier wave ACK/NACK bit, wherein N is integer.Correspondingly, by using more possible in more resource blocks and/or resource block Cyclic shift indicates multiple ACK/NACK values, can be designed to uPUCCH to adapt to two or more ACK/NACK.Such as Fruit sends uplink control data using two or more resource blocks at box 1708, then uses the circulation of a RB Displacement can be same or different with the cyclic shift of another RB.

It gives one example, it can not include: to send regularly CSI to report that uplink control data is sent at box 1708 It accuses.In this case, communication component 661 can based on 1-ms TTI (for example, alternatively using the PUCCH in LTE) come Report regular CSI.Thus, for example, it may include: transmission uPUCCH that uplink control data is sent at box 1708, but UE 1202 additionally can be triggered or be configured as to send PUCCH simultaneously or in different TTI.

In another example, other than 1- symbol uPUCCH, uPUCCH can take up two or more symbols.Cause This, for example, TTI determines that component 1212 can determine the different TTI (for example, symbol) for sending control data.In addition, communication Component 661 can determine the different resource block in different TTI to send control data, make it possible to achieve frequency diversity gain. It gives one example, communication component 661 can determine will use different RB in two TTI (for example, 2 symbols), so that can It is transmitted to send 2- symbol uPUCCH (for example, if using RB index n's in a symbol with the mirror image jump of frequency of use Words, then can use RB index N-n in the second symbol, and wherein N is the sum of RB, for example, its uplink for being equal to multiple RB Road bandwidth).For example, communication component 661 can in response to by the received 2- symbol downlink transmission of communication component 661 and/or The downlink transmission of various durations (for example, 1 symbol) sends 2- symbol uPUCCH.
